Autoexpand does not work for axes

[shadow-identity]

Seems like autoexpand does not work (or I do something wrong). In the example below, I increased y axis tick label size and font size, so they consume much more space, but margins are not adjusted, and labels are partially hidden outside of the chart container.

Reproduction

https://codepen.io/shadow-identity/pen/abeQprO

This is slightly modified example from the documentation: https://plotly.com/javascript/line-and-scatter/#line-and-scatter-plot

What is modified:

• y axis tick values increased to have more symbols
• y axis tick font size increased
• I also tested it with explicitly set margin: {autoexpand: true}, but it does not change anything

Expected results

Grid size should be reduced (margin should be added to the left) to keep y axis ticks visible

Actual results

Y axis ticks are partially hidden

Environment

Chrome 130, Firefox 133 beta
Plotly from https://cdn.plot.ly/plotly-2.35.2.min.js

Additional info

At the same time, legend seems to increase corresponding margin. I increased the name length of one of the series to check if it will expand the margin, and it works.

OK, I found that additionally to autoexpand user have to set automargin: true on axes. I think it would be great to mention this in autoexpand documentation, because it is very unclear, especially if you just trying to use the library for the first time.

thanks for following up @shadow-identity - I'll see if we can get it into the docs for an upcoming release.
